The original print measures 14 in × 111⁄4 in (35.6 cm × 28.6 cm). The lithograph depicts a large building roofed by a never-ending staircase. Two lines of identically dressed men appear on the staircase, one line ascending while the other descends. Two figures sit apart from the people on the endless staircase: one in a secluded courtyard, the other on a lower set of stairs. While most two-dimensional artists use relative proportions to create an illusion of depth, Escher here and elsewhere uses conflicting proportions to create the visual paradox.

The two concentric processions on the stairs use enough people to emphasise the lack of vertical rise and fall. In addition, the shortness of the tunics worn by the people makes it clear that some are stepping up and some are stepping down.

The structure is embedded in human activity. By showing an unaccountable ritual of what Escher calls an 'unknown' sect, Escher has added an air of mystery to the people who ascend and descend the stairs. Therefore, the stairs themselves tend to become incorporated into that mysterious appearance.

There are 'free' people and Escher said of these: 'recalcitrant individuals refuse, for the time being, to take part in the exercise of treading the stairs. They have no use for it at all, but no doubt, sooner or later they will be brought to see the error of their non-conformity.'

Escher suggests that not only the labours, but the very lives of these monk-like people are carried out in an inescapable, coercive and bizarre environment. Another possible source for the people's looks is the Dutch idiom "a monk's job", which refers to a long and repetitive working activity with absolutely no practical purposes or results, and, by extension, to something completely useless.
